WINDOW-LOCKING DEVICE.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed July 15, 1912. Serial No. 709,476.

To all whom it may concern:

Be it known that I, FRANK B. RULLMAN, a citizen of the United States,residing at Hiawatha, in the county of Brown and State of Kansas, haveinvented certain new and useful Improvements in VVindow-Locking Devices;and I do hereby declare the following to be a full, clear, and exactclescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus forholding window sash open and closed and comprises a simple and efficientdevice of this nature having various details of construction andcombination and arrangements of parts which will be hereinafter fullydescribed and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a side elevation showing the application of the sash holding deviceto the sash of a window. Fig. 2 is a vertical sectional View showing anedge view of one of the sash with the keeper attached thereto, and Fig.3 is a perspective View showing the keeper and the retaining device.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the window, B the lower sash and C the uppersash. Secured to the face of the upper sash is a plate D forming akeeper which has a portion intermediate its fixed end outwardly bowedand provided with a transverse slot E. F astened to the inner face ofthe lower sash is a plate F which extends above the up or surface of thesash and has its ends sp it, forming two angled resilient fingers,designated respectively by letters H and K, the former of which isadapted to contact with the bowed portion of the plate D when the windowto which the plate F is secured is raised a sufficient distance, or theupper sash lowered, the plate F springing away from the plate or keeperD and, when the end H comes opposite the slot E therein, it is adaptedto spring into said slot and serve as a means to prevent a furthermovement of the sash to which the plate is attached in one direction.Said keeperD may be fastened to the upper sash at any suitable locationand it will be noted that, when the angled finger H engages the slottherein, it will prevent a further raising of the sash B. The finger Kserves as a handle, affording means whereby the plate F may be sprung sothat the end H will disengage the slot to allow the upper sash to belowered.

It will be understood that the keeper may be placed anywhere upon onesash, while the plate with angled fingers may be secured to the othersash, thus affording means for locking the sash closed or raised at anydesired distance. i

What I claim to be new is A window fastener comprising a bowed socketplate wit-h a transverse slot therein and adapted to be fastened to theface of a sash, a resilient strip fastened to the inner face of anadjacent sash and having its outer face flush with the face of the sashto which it is secured, said plate being bent at a slight angle oppositethe top of the sash to which it is fastened and its free end bifurcated,each wing being bent at an angle at a location midway its length, thetwo bent portions of the wings being at right angles to each other, oneadapted to engage the slot of the keeper and the other serving as ahandle, as set forth.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
